xtts 跨平臺遷移數據庫

建議xtts目錄和/rman 備份的路徑目錄都使用nfs共享


alter system set deferred_segment_creation=false sid='*' scope=spfile;

###########################增量臨時文件在asm#########xtt.properties ##########################
tablespaces=SPROD_TBS,IDX_TBS
platformid=13
dfcopydir=/xttrman/full 本地全量備份數據的路徑
backupformat=/xttrman/incr 本地增量備份數據的路徑
stageondest=/xttrman/full 目標端所須要恢復數據的路徑,後續生成的增量也要拷貝到這裏
storageondest=+DATA/prod/datafile 目標端數據文件路徑 -c 的時候放的位置
backupondest=+DATA/prod/datafile 目標端增量文件的臨時路徑，作完增量後會自動刪除，若是放asm須要設置asm_home和asm_sid
asm_home=/oracle/app/grid/product/11.2.0/grid
asm_sid=+ASM
parallel=2
rollparallel=2
getfileparallel=2

源端全量備份腳本
cat full_backup.sh 
export TMPDIR=/oracle/soft/xttconvert
perl xttdriver.pl -p

源端執行全量備份
sh full_backup.sh

生成文件
[oracle@localhost xttconvert]$ cat xttplan.txt 
SPROD_TBS::::967892
5
6
IDX_TBS::::967892
7

[oracle@localhost xttconvert]$ cat xttplan.txt 
SPROD_TBS::::967892
5
6
IDX_TBS::::967892
7
[oracle@localhost xttconvert]$ cat rmanconvert.cmd
host 'echo ts::SPROD_TBS'; 
convert from platform 'Linux x86 64-bit' 
datafile 
'/xttrman/full/SPROD_TBS_5.tf' 
,'/xttrman/full/SPROD_TBS_6.tf' 
format '+DATA/prod/datafile/%N_%f.dbf' 
parallelism 2; 
host 'echo ts::IDX_TBS'; 
convert from platform 'Linux x86 64-bit' 
datafile 
'/xttrman/full/IDX_TBS_7.tf' 
format '+DATA/prod/datafile/%N_%f.dbf' 
parallelism 2;

目標端，執行恢復轉換
vi convert.sh
export XTTDEBUG=1
export TMPDIR=/oracle/soft/xttconvert
perl xttdriver.pl -c

sh convert.sh

vi do_incr.sh
export TMPDIR=/oracle/soft/xttconvert
perl xttdriver.pl -i


源端增量備份
sh do_incr.sh

[oracle@localhost xttconvert]$ cat xttplan.txt.new 
SPROD_TBS::::968168
5
6
IDX_TBS::::968196
7
[oracle@localhost xttconvert]$ cat tsbkupmap.txt
IDX_TBS::7:::1=07u31cir_1_1
SPROD_TBS::5,6:::1=06u31ciq_1_1


注意每次作完增量 須要將增量的數據文件拷貝到全量備份的目錄下，恢復完刪除/xttrman/incr/*
cp /xttrman/incr/* /xttrman/full/

目標端增量恢復
vi restore_incr.sh
export TMPDIR=/oracle/soft/xttconvert
perl xttdriver.pl -r


注意若是增量恢復文件放在asm可能會出現如下錯誤，能夠忽略，這個是xtts沒法自動刪除asm的臨時文件

下次增量要記錄當前恢復的scn位置，產生最新 xttplan.txt 文件要否則下次增量還會在全量進行備份
perl xttdriver.pl -s

後續增量循環如下三步驟
sh do_incr.sh
sh restore_incr.sh
perl xttdriver.pl -s


最後一次增量，表空間設置爲只讀模式
SQL> alter tablespace SPROD_TBS read only;

Tablespace altered.

SQL> alter tablespace IDX_TBS read only;

Tablespace altered.

最後一次恢復
sh do_incr.sh 
sh restore_incr.sh


導入元數據，建議不要導入統計信息，目標庫直接收集
create or replace directory xtts_dir as '/oracle/soft/'
create database link ttslink connect to system identified by "oracle" USING 'sprod';
